The tunnel is windy to the instant freezer that freezes up and down
Technical field
The utility model relates to a kind of tunnel type instant freezer, belongs to freezing equipment.
Background technology
CN2563524 and CN 2166389 disclosed freezing equipments; Constitute by insulation casing, automatically controlled, evaporimeter and conveyer belt; Evaporimeter is positioned at the conveyer belt top; The frozen matter article can only unidirectional (being top) be accepted the cold wind that refrigerating evaporator and axial flow blower blow out, and the frozen matter article are caught a cold unbalanced, influence cryogenic temperature and freezing freshness.
Summary of the invention
In order to solve the technical problem of above-mentioned existence, the utility model provides a kind of upper and lower two-way refrigeration, the frozen matter article is caught a cold evenly, the tunnel type instant freezer that refrigerating effect is good.
The purpose of the utility model realizes through following technical proposals: the tunnel is windy to the instant freezer that freezes up and down; Comprise electrical control cubicles and insulation casing, annular transmits the gateway, two ends that stainless steel band passes the insulation casing, at the insulation box house; The top that annular transmits stainless steel band is provided with refrigerating evaporator, axial flow blower, centrifugal blower; It is characterized in that: be provided with down the refrigeration evaporator pipe in the cavity of described annular transmission stainless steel band, last refrigerating evaporator is connected with the refrigeration feed pipe, and following refrigeration evaporator pipe is connected through adpting flange with last refrigerating evaporator; Following refrigeration evaporator pipe is connected with the liquid storage cylinder; The liquid storage cylinder is connected with the liquid boost pump, and the liquid boost pump is connected with the refrigeration liquid back pipe, and reach down the end face of refrigeration evaporator pipe is respectively equipped with centrifugal blower at last refrigerating evaporator top.
Also comprise the defrosting water inlet pipe, the defrosting water inlet pipe is divided into two-way defrosting water pipe after penetrating the insulation casing, and one road defrosting water pipe is positioned at the refrigerating evaporator top, and another road defrosting water pipe is positioned at refrigeration evaporator pipe top down, is provided with the defrosting downcomer at the insulation bottom half.
Described incubator body side surface is provided with thermal insulating door thermally insulated door.
The beneficial effect of the utility model: the utility model adopts said structure; Owing in annular transmission stainless steel band, in the cavities refrigeration evaporator pipe down is set; And at last refrigerating evaporator and following refrigeration evaporator tube end centrifugal blower is set respectively, and two-way refrigeration, a plurality of centrifugal blowers are windy to blowing a cold wind over; Make the frozen matter article catch a cold evenly, quick-frozen is effective; The defrosting water pipe is set in insulation in the casing, the frost on can timely and effective removal vaporising device is avoided influencing refrigeration because of frosting.At the incubator body side surface thermal insulating door thermally insulated door is installed, easy access personnel turnover.
